Which of the following is NOT a cabling technique?

The choice of diagonal as not being a cabling technique is correct because the terminology used in cabling systems typically refers to specific arrangements and patterns that provide support and structural integrity to trees.

Cabling techniques such as triangular, direct, and box or rotary involve specific configurations that help to stabilize branches or trunks to prevent failure during adverse conditions. For instance, the triangular method creates a stable support that can effectively distribute the weight of branches and reduce stress on weak areas. Similarly, direct and box or rotary techniques develop cabling systems that allow for movement while also providing necessary support to prevent structural collapse.

Diagonal, however, does not align with established cabling practices. While the term may suggest a method of support, it is not recognized as a standard technique like the others listed. This distinction highlights the importance of using correct terminology and methods within arboricultural practices to ensure effective tree care and management.
